air in radiators

[adamb]

can any one help, i moved into a bungalow a year ago, my boiler is in the garage at the gable end of the house with a small walk way seperating the garage from the house. The feed and return split in the garage and feed the radiators in the house one set on radiators in the front of the house and the other feeds the radiators in the back of the house, a simple split, The problem i have is the first radiator on each side of the house keps air locking i keep bleeding these on a weekly basis. When the pump switches on for the first time what sounds like is a lot of bubbles rushing through the system, the rest of the radiators are ok the fault lies between the first radiators on each side of the house and the boiler in the garage, being a DIY person could someone tell me what i can do to test for a leak or solve the problem.
Many thanks

SOunds like a design probem, sucking air in when the pump starts. Can be cause by a blockage due to sludge though. You need a guy to be there to look at it.
